Patented Apr. 22, 1930 UNETED STATES JAMES EDW. GUN'IE-R, or BALTIMORE,MARYLAND CONTAINER" Application filed. April 1,

My invention relates to new and useful improvements in closures forcontainers, and more particularly to one in which the closure retainingmeans may be readily removed,

and that without destroying the further usefulness of the container.

An object of the invention is to provide a sealed closure which may beeconomically manufactured and applied, and which can be easily andcertainly opened without the use of any tool, and a cap which, after thecontainer is opened, may be satisfactorily used for closing thecontainer, while the contents are being used.

Another object of my invention is to make such a container the cap ofwhich may be uniform over its surface, so that when the retaining ringor band is placed upon the cap it need not be definitely located inrelation to any particular configuration of the cap.

Further objects and advantages will be apparent from the preferred formshown in the accompanying drawings:

Figure 1 is a plan view of the container and cap with a ring being shownpartly in dotted lines.

Figure 2 is a cross sectional view on line 22 of Figure 1 looking in adirection of the arrows.

3o Figure 3 is a partial cross sectional view on line 3-3 of Figure 1.

Figure 4: is a plan view of the ring or band alone.

Figure 5 is a front view of the ring or 35, band alone.

Similar numerals refer to similar parts throughout the several views.

The container body 1 has a flared mouth 2. The cover or cap 3 has anoutwardly and up- 40 -wardly'directed shoulder 4 and the extreme lip 5of the cap rests upon the lower part of the flared mouth 2 of thecontainerv and there is a tight seal between these two surfaces. Theretaining ring or band 6 rests in the groove formed by the lip 5 and theshoulder 4 of the cap and pressesinvvardly and clownwardly upon the cap,thereby forcing the cap into sea-led relationship with the containerbody. The retaining ring or band 6 comprises 51%;:two turns of a spiralin the shape of a sec- 1926. serial No; 98,998.

tion of an inverted cone, that is, the top perimeter is greater than thebottom, so that the upper turn of the spiral presses downwardly on; thelower turn which; as above stated presses the lid firmly against thecontainerbody. The lower endof the ring or band? is tapered as shown in-Figure 5 and, returning upon itselfthe spiral on aslight angle risestothe second turn,;as also shownin Figure 5 and the second turn isslightly larger than the first turn. The second turn above-the point ofthe beginning of the spiral is directed inwardly towards the' ring orband center thereby forming a handle 8 for the removal of the ring. Thecap 3 has deep pressed portions 9 on each side, the facingsides of whichare approximately at right angles to the cap,the reby forming a handlefor the removal of the cap. Such deep pressed: portions are oftenreferred to as oyster ears. The upper portion of the flared mouth of thecontainer is bent over the upper coil of the retaining ring or band asshown at 10. This bent over edge must extend far enough in toward thecenter of the container to pass beyond the line of force eX- ertedupwardly by the container cap and the coils of the spiral ring or band.At thepoint where the handle projects from the ring or band thisinturned flange of the container mouthis held upwardly slightly by theprojecting handle as at 1-1, that is, the flange is notbentdownintoclose contact with-the ring I or band-at this point as it is throughoutthe rest of its course. p

In assembling the container the cap may be placed within the mouth ofthe container v and the ring for band dropped in with the handleprojecting inwardly and it may be in any position around the cap sincethe projecting handle does not have to go into any slot in the cap. Themouth of the container is then bent over-the upper part of the ring orband so that it overlaps it slightly. When it is desired to remove thecap, the handle is first pulleddirectlyupward thereby prying out thein-turned flange at. the point of the] handle, and the ring orband isthen pulled directlynpward and around the can body, prying: the flangeopen attend; the

mouth of the body, until the ring or band is removed, and the cap isthen removed by means of lifting on the oyster ears.

The retaining ring or band may be made any shape in cross section or ofany material which will hold its form under the stresses to which it issubjected, and which has sufficient tensile strength to be pulled out.

As many changes might be made in the above arrangement, and as manyvariations may be made in the art above described without departing fromthe scope of the invention, it is intended that all features hereindescribed or shown in the accompanying drawings shall be interpreted asillustrativ only. r

I claim:

1. In a container, a cap fitting within and being upheld by thecontainer wall, an upwardly and outwardly directed shoulder on said cap,a retaining band having a top of greater perimeter thanitsbottomwithin'the container and abutting against said shoulder, said wallpartially overlapping the band, thereby holding it in its shoulderabutting position. 7 I

2. In a container, a cap fitting within an open end of the container,means formed upon the interior of the container wall adjacent said openend adapted to be engaged by and to support said cap, an upwardly andoutwardly directed shoulder on'said cap, a retaining band having a topof greater perimeter than its bottom within the container abuttingagainst said shoulder, said wall partially overlapping the band, therebyholding it in its shoulder abutting position.

3. In a container, a cap fitting within and being upheld by thecontainer wall, an upwardly and outwardly directed shoulder on said cap,a retaining band comprising two turns of a spiral within the containerand abutting against said shoulder, said wall partially overlapping theband, thereby holding it in its shoulder abutting position.

4. In a container, a cap fitting within and being upheld by thecontainer wall, an upwardly and outwardly directed shoulder on said cap,a retainingband comprising two turns of a spiral within the containerand abutting against said shoulder, said wall partially overlapping theband, thereby holding it in its shoulder abutting position, a portion ofone of the turns of said spiral projecting from said shoulder andoverlapping wall,

thereby forming a handle for the removal of said band. r

5. In a container, a cap fitting within and being upheld by thecontainer wall, an upwardly and outwardly directed shoulder on said cap,a partially rotatable retaining band having a top of greater perimeterthan its bottom within the container and abutting against said shoulder,said wall partially overlapping the band, thereby holding it in itsshoulder abutting position, and said band having a projecting handle bywhich to partially rotate a section of said band, and by which to removesaid band.
